Referring particularly to Figs.'1 and 2, the reference numeral Imaydenote, generally', an ad,-

justable angle insulated trolley wire crossing-fix.-

ture for providing a smooth crossing between the intersecting trolleywires I2 and I4, which it is desired to insulate from each other.

In' order to provide a smooth crossing between the ytrolley wires I2 andI4 without interrupting .the continuity of the trolley wires, thetrolley wire xture I6 may be provided withsuitable means, such as theelongated metallic body member lI6 for positioning the trolley wire I2so as to deflect ita'nd carry it over the trolley wire I4, in spacedrelation thereto. Suitable means', such'as the end members I8, may beprovided, having depending lips 20 which may be peened about the trolleywire to secure it to the bodyl member 'I6 and maintain the adjacentportions thereof lector alongk the trolleywire I2, suitable means, l

in the proper operating relation relative to the trolley wire I4. n Y YInorder -to'provide for guiding a current colsuchas the renewablemetallic wear members 22 may be positioned along the lower side of the vbody member and ysecured thereto in any suitable manner, Asuch forexample, as by means of transverse bolts 23.

WithY a view to maintaining the trolley wire I4 in the proper operatingrelation to the trolley wire I2, an adjustable trolley crossing member24 mayr beprovided. The crossing member 24 4may be'secured to the bodymember I6.-.in any l suitable manner, being for example, pivotallymountedon the lower side of the body member adjacent,r the centralportion thereof, so as to Vbe adjustable to different angular positionsin the horizontal plane, such for example, as shown in dot and dashlines in Fig. 2. End members I 8 vof a welle'known type may be utilizedfor securing the trolley wire I4 to the crossing member, having lips26vwhich may ,ber peened about the wire in the manner shown.

. In order to insulate the crossing member 24 from the body member I6van insulating member 26 of any suitable insulating material may beinterposed between these members, in a manner hereinafter described indetail.

Renewable metallic runner guide members 28 may be positioned inalignment Vwith the wear members 22 on each side of the crossing member24, and insulating runner members 36 may be interposed between therunner guide members 23 and the metallic wear members 22, to insulatethem from eachother, and insulate the adjustable crossing member fromthe body member I6.

`Referring particularly to Figs. 3, 4 and 5 of the drawings, it may beobserved that the body mempor-tions 42, interfitting therewith soy as tointerlock therewith and thus secure the trolley wire I2 in the properoperating relation in the groove 38 of the body member I6.

Suitable means, such as the depending ears 44, may be provided onv thebody member I6 for securing the insulating member 26 thereto. Forexample, rthe ears 44 may be positioned on the lower side of the bodymemberadjacent the central portion thereof, and provided with elongatedopenings 46 therethrough, for receiving the bolts 23 which secure therunner members 22 and the insulating member 26 to the body member IS andin operating relation to each other. The openings 46 may be elongated toallow limited movement of the bolts 23 therein and provide for securingthe insulating member 26 to the body member I6 in iloating relation. Thebody member I6 may thus be deformed without stress-A ing the insulatingmember 26. Suitable means such as, for example, the laterally projectinglugs 48, may be provided for effecting an interlocking relation withportions of the wear mem) bers 22, in a manner which will be hereinafterdescribed in detail.

Referring particularly to Figs. 6, 7 and 8, it may be seen that theinsulating member 26, which may be of any suitable insulating material,such as wood, bre, molded resin, or the like, may comprise an elongatedbody member having upstanding `side portions 49 defining a centralgroove 50 along the upper side. Suitable slots or recesses 52 may beprovided in the ends of the insulating member for receiving thedepending ears 44 on the body member I6. may be provided in Ithe spacedend projections 56 which define the slots 52, for receiving the bolts23, whereby the insulating member 26 may be secured to the body memberI6. Suitable means, such as the wear bushing 60, which may comprise alength of tubing or the like, may be inserted in the lower side of theinsulating member 26 for positioning the adjustable trolley crosse ingmember 24, and protecting the insulating member from wear which might beoccasioned by movement of the crossing member relative to the bodymember I6.

Referring particularly to Figs. 9 and 10, which are enlarged sideelevation andV cross-section views, respectively, of the adjustabletrolley crossing member, it may be seen that this member may comprise asubstantially vchannel-bhaped elongated body member 62, having a groove65 along the upper side thereof for receiving the trolley wire I4. Thebody member 62 may be provided with a bearing plate comprising thelaterally extending flanges 66 positioned on op- 'posite sides of thebody member adjacent the central portion thereof. Suitable means, suchas the runner portions 6'I and 68 may be provided on the lower side ofthe body member for guiding a current collector therealong. A centrallypositioned guide boss 'II may be provided between the spaced ends of therunner portions 61 and 68 to facilitate guiding a current collectorthrough the intersection. y

The end portions of the body member 62l may be. suitably `shaped for`securing 4the end members I8 thereto, being, ;for'example, providedwithnotched orfrecessedportions,12 for interlocking with correspondinglyshaped portions on the end members `I8 in the manner shown. l

With a View to pivotally positioningthe adjustable crossing member 24relative to the body member I6 of the fixture, a bifurcated boss 'I3 maybe provided on the upper side of the crossing member, which is adaptedto be positioned in the wear bushing 66 of the insulating member 26.

Referring particularly to Figs. 11 and -12 of the drawings which areenlarged side elevation and end views, respectively, ofthe runner guidemembers 28, it will be observed that these guide members may comprise arunner member 'I6 with a graduallyI rounded end portion 'I'I andan`interior recess 'I8 `at the other end thereof. In order to Ysecure theguide members "28 Vin the desired operating relation to the body memberI6, they may be provided with the spaced apart arms 80, adapted toextendupwardly on either side of the insulating member 26.A The arms 86may be substantially Lshaped, as shown in Fig. 11,

having horizontal portions `B2 thereof which lie along the sides of theinsulating member, and which have openings 84 therein for receiving thebolts 85 whereby the runner guide member may be secured to theinsulating `member so that the point of support is positioned alongtheaxis about which it tends kto `rotate when struck by a passing currentcollector. In this manner the guide member may be simply and efficientlysecured to the insulating member 26. `By so positioning the runner guidemembers 28"that the rounded end portions 'I'I project over the laterallyextending flanges 66 of the` adjustable crossing member 24, the crossingmember may `be suitably retained in operating relation with the bodymember I6 of thexture.

The details of the renewable wear members 22"are shown in Figs. 13, 14and 15. With a View to increasing the lire of the Iparts of the trolleycrossing xture which` are most subjected to wear, the wear member 22 maybe made of any suitable`metal having good wearing qualities. The Wearmember 22 may, for example, comprisewan elongated channel-shaped runner`member portion 96 for guiding a current collector, having a recess 92at one end for engaging an extension oriprojection on the insulatingrunner member 36. The wear member 22 may be secured to the body memberI6 by means of the upwardly pro-4 jecting ears 94, which may behook-shaped, having a slot 96 therein for receiving the projecting lug4B on the body member I6 to effecten interlocking relation between `thewear .member 22 and the body member I6 at one end. l At the other `endof the wear member, oppositely positioned upwardly projecting ears98`may be provided at each side of the member.V The ears 98 may beadapted to extend up about` the end portion of the insulating member26,' and may be provided with substantially 4horizontal shoulderportions 99 which are adapted to engage the lower sideof the insulatingmember 26 for assisting in supporting it. Openings 100 frnay be providedin the `ears 98 for receiving'the bolt 23, which secures the wearlmember andthe insulating member 26 to the body member I6. i f

In order to insulate the metallic wear members 22 fromthe runner guidemembers 2B which engage the flanges 66 of :the adjustable crossingmember 24, `suitable means. such,` for. example,

used.

as the insulating runner members .36 may be provided. The insulatingmembers 30 may, for example, comprise an elongated body memberofanysuitable insulating. material having relatively good wearingqualities, and having a crosssecton similar to'that of the runner memberportions of the wear members 22. End projections |62 of reducedcross-section may be pro- `vided at each end for positioning in therecesses in the guidemembers andthe runner member portions 90 of thewear members 22.

Inassembling a trolley crossing xture embodying the principal` featuresof my invention, the` bodymember I6 may be positioned with the trolleyWire I2 in the groove 38 thereof. The endmembers I8 may then be placedin position with the notched end portions 4I engaging thecorrespondingly notched end portions 42 of the body member, and the lips20 may beV peened about the trolley wire, thus securing thebody memberI6 to the wire and positioning the-adjacent portons of thetrolley wireI2 in the proper relation to the trolley wire I4;

Theadjustable trolley crossing member 24 may then be secured to thetrolley Wire I4 by positioning the wire I4 in the groove 65 and securingthe end members I8 to the adjustable crossing member. The insulatingmember 26 `may be positioned between the vcrossing member 24 and thebody member I6, with the bifurcated boss'IS positioned in the wearbushing 6,6, and the upstanding sideportions 49 positioned about thecentral portion 40 of the body member I6.

-The runner guide members 26 may "then'be secured to the insulatingmember 26V by inserting the bolts 85 through the openings 84 in the arms86, and through the insulating member. The insulating runner members 36may be positioned l-With the end projections |62 thereof inthe recesses92 of the guide members 23. The ree Vnewable wear members may thenbesecured to the body member I6 by hooking the ears 94 about thelaterally projecting lugs 481011 the body memben-and then bringing theother end vof the wear member up against the insulating member 26, andinserting the'bolts 23 through the openings |66 in the ears 98, theopenings 54 in the insulating member, and the openings '46 in thedepending ears 44 of the body member I6. Inasmuch as the body member I6of the trolley crossing Ill is naturally subjected to bending stressesby the trolley wire I2,` which .isi de- `formed from its free position,it will be realized that when the body member I6 is connected in anoverhead trolley system, deformation thereof results. Since it isessential in modern highspeed trolley systems to provide the maximumpossible smoothness in the current collector guiding portions, suchvdeformation, as it resultsin a corresponding. change in the relativepositions of the-runnermembers positioned on thebody member I6, isgreatly detrimental to the proper `-operation of the overheadsystem inWhich it is The runner members tend .to become bowed or warped out ofalignment with each other, and a rough spot results.

In order to neutralize the-harmful effects o the deformation of the'bodymember of the trolley fixture when it is subjected to bendingstresses by the trolley Wire being connected thereto, the runner membersmay` be purposely provided with a slight angular difference betweenthem, measured in a vertical planey The body member `may be initiallyprovided` with. an

additional amount of bow, or the wear members may be secured thereto ata slight angle,

t or both means may be used to attain the result. For example, by soshaping the body mem- 5 ber` IB that in the free position it has theshape outlined by the dot and dash lines in Figs. 1 and 4, and whenconnected in the trolley system adopts the shape shown in the fulllines, the runner member portions 90 and the insulating l0 runnermembers 30 associated therewith at the two ends of the body member maybe initially positioned so that the ends adjacent the end members' I8are slightly depressed, or the other ends slightly raised. Upon theconnectionl of the trolley wire I2 vto the body member I6, the f bodymember will be deformed, and the runner members at veach end of the bodymember will be brought into alignment with each other, providing asmooth surface for guiding a current collector therealong.

From the above description, taken in connection with the accompanyingdrawings, it will be apparent that by my invention I have provided in asimple and eiective manner for neutralizing the harmful eifects ofdeformation in the body member of a trolley fixture so as to provide asmooth underrun for guiding a current collector. By positioning theinsulating member and Supporting it in floating relation relative to thebody member in the manner herein disclosed, and using a metallic bodymember for resisting the stresses exertedl by the trolley wire in acontinuous trolley wire insu@ lated crossing fixture, I have reduced themechanical stresses normally incident to the insulating member, and havethereby greatly increased the life thereof. By providing renewable wearmembers having portions thereof interlocking with portions of the bodymember, the installation and replacement of the wearing parts is greatlyfacilitated, and the cost of installation and servicing arecorrespondingly reduced.

Since certain changes may be made in the above description, anddifferent embodiments of .the invention may be made without departingfrom the scope thereof, it is intended that all theY matter contained inthe above description,

f or shown in the accompanying drawings, shall be considered asillustrative, and not in a limiting sense.
